In a test I have a long table with about 100 questions. All questions are grouped in, let say, 10 "categories", so every time an user answers a question he adds a value to the corresponding "category".
I would like to show the user his test results in a new page:
Cat. A 12% (or total points)
Cat. B 18% (or total points)
....
Cat. N 25% (or total points)
A sorted list (ordered from max to min) would be better.

I have ten totals like this
document.getElementById('CatA').value = sum; ... then sum 1, sum 2...
but i am not able to write each sum to a table in a new page.

Please note that I do not have server side technology, php mysql or whatever.
Xml seems to be a possible solution, but it is complicated for me.
Any suggestion?

Thank you for the hint. The tutorial helped me a lot.
Now my problem is to display the results in a user friendly way.
A CSS styled table with bar graph, as the ones used in poll results, would be great. For example:

<div class="answer_box"><div class="answer_percent" id="answer1_percent" style="width:15%;">&nbsp;</div></div>
<div class="answer_votes">15%</div>

So I need every result as a percentage AND written twice (as above).
As far as I understand from the tutorial you get a location.search string formatted and splitted like this:
mySearch = location.search.substr(1).split("&")

The array of objects created is used in the following function:


function getFromSearch() {
var x = 0
mySearch = location.search.substr(1).split("&")
for (x=0;x<=mySearch.length;x++) {
eval("document.forms.myNewForm."+mySearch[x])
}
}

So, is it possible to change the results in a percentage and write them styled as above css?

After further searches in JavaScript Kit I found Graph-it!, to create graphs out of raw data.
Exactly what I need, a graph with percentages.
My problem now is that the script is based on a multi-dimensional array:


//DEFINE GRAPH VALUES [Item name, absolute value]
var graphx=new Array()
graphx[0]=["CNN",60]
graphx[1]=["MSNBC",75]
graphx[2]=["ABC News",24]
graphx[3]=["BBC News",52]

On the other end, the getFromSearch function creates a normal array of objects named mySearch. Each will look like this:
myValue=AEIOU
and the results are displayed in a text box.

What I am looking for is a method to create two arrays
(one for item name and one for absolute values extracted by mySearch) that automatically fill my graph.
Any idea?
Thanks for your help.
